Understanding the factors that influence plant establishment and growth is crucial in ecology and conservation biology particularly for species that are difficult to reestablish. One such species is Amorpha canescens (leadplant) that is considered of high conservation value, but often absent from prairie restoration projects. To address this problem, we tested how different soil types (homogeneous vs. heterogeneous), seed sowing treatments (spatially aggregated vs. uniform), and patch size (large vs. small) influenced the abundance of A. canescens in plant restoration experiments that began in 2017. In the summer of 2023, we quantified the aerial cover of A. canescens in plots representing different treatment combinations. We found that the A. canescens cover was highest when seeds were sown in an aggregated spatial arrangement for plots composed of heterogeneous soils. This effect was stronger in plots comprised of small rather than large sized patches. In plots with homogeneous soils, A. canescens cover also appeared higher under aggregated compared to uniform seed sowing, though this difference was not significant. Amongst individual patches of large scale and heterogeneous soils, A. canescens produced more cover in certain soil types than others. There were no differences in the cover among soil types in small scale patches. These results suggest that A. canescens cover is highest when isolated from other plant species particularly in heterogeneous rather than homogenized soils. Furthermore, restoration of A. canescens in former tilled fields may benefit from sowing or planting seeds in aggregated rather than uniform spatial patterns.
